Building owners

Vegetated roofs offer exciting opportunities for architectural design, such as allowing a building to merge with the surrounding landscape, provide a dramatic accent, or reinforce the defining aspects of the structure's geometry. Vegetated roofs may also help enhance property values in cities where outdoor space is limited, create calming communal spaces in urban areas, and help with meeting local code requirements.
